Re: Not one single person has answered my MC1530 posting correctly

Hmmm, it's also a UNIXism for releasing the current window. cntl-Z gets me back my window (from another program), and when followed by a bg (background) the program executing in that window gets another process in the background (effectively another widow).

I thought you just meant that Jim could multi-task effectively. ;-)

Taking Teletubbianism a step further, how about "My Pictures". Then there are programs that set up "folders" like "My Music" and "My Ebooks".

But as gay as these folder names are, I can't knock Redmond for being condescending. Sometimes you *have* to take people by the hand - people who don't want to learn about computers but just want to use them. When Inet took off and the prices dropped, everyone and their grandmother bought computers. Most of these people never heard of DOS or the "any" key. So rather than ask a user to create a *directory* to store their documents, you just give them a default since, chances are, when the "save as" dialog pops up, they're just going to click save. This way a tech support droid can probably help them find their stuff in "My Documents" and not have to introduce them to Explorer and Search.

Typically Undo in Windows.

Oh dear - now Jim can't hear me telling him that he's failed to produce the correct expression for VOUT on his web-site for his op-amp: clue - the open and closed brackets should match.

The origin was before MS-DOS on the 8088. It was for backward compatibility with files transfered from CP/M. Microsoft Basic [1975-1981] for the 8080 used Ctrl-Z to detect EOF because CP/M by Digital Research used it. CP/M did not record the file size in the directory, only the sectors used. So to find the actual file size, you looked for the ending padding of Ctrl-Z's that were written to the last sector. This was riding on IBM's development of the 8" floppy disk (that was used in the System 34 (?) workstation) which Shugart got down to a reasonable price -below $2000.

Ctrl-Z to Western Union and AT&T TeleType meant Substitute Character, so if there is any Unix connection, it would have to come from the original operating system for the PDP- series of computers back in the late '60's and not be just another editing keystroke.

I'll have to eyeball that again. In the mean time, I'm a transponder ;)

I just hate trying to type equations. I did it with pencil and paper, verified the numbers, the tryped :-(

It is a pain, isn't it. Lack of subscripts doesn't help. A screen shot of a math cad app is about the best we could do.

But Andy's ASCII art helps to see things better and it speeds entry.

Uh, if Rick's talking about the very last end parentheses on the Vout eq., it's not even worth commenting or wasting time on. It doesn't mess anything up.
